酶法富集甘油酯型n-3 PUFA的研究进展Research progress on enzymatic enrichment of glyceride-type n-3 PUFA
n-3多不饱和脂肪酸(n-3 PUFA)是人体生长和健康不可或缺的一类脂肪酸。然而,天然甘油酯中的n-3 PUFA含量较低,限制了其利用价值。随着食品、医药、母乳脂替代和保健品等行业对高含量n-3 PUFA需求的不断增长,富集n-3 PUFA甘油酯已成为研究热点。其中,酶法富集因高效、绿色环保等优势,受到研究者的青睐。旨在为绿色高效酶法富集甘油酯型n-3 PUFA的研究与应用提供理论指导,综述了酶法富集n-3 PUFA甘油酯中脂肪酶的筛选、酶法富集技术路线和反应体系优化的研究进展。酶法富集n-3 ...

本发明公开了一种微型质谱中样品直接进样在线富集的膜进样装置,采用无孔致密聚二甲基硅氧烷片状膜,能够有效限制进入质谱的气体量,同时可以做为质谱和大气的中间接口。装置中采用了单层超薄膜对样品进行快速富集,膜后具有一真空差分腔体,该腔体用来进行富集样品的缓冲和存储。该腔体处于低真空条件下,所以允许加大膜的面积,从而加大样品与膜的接触面积,富集效率提高。差分口处安装有电磁阀,当要进行气体富集时关闭抽气口,气体经过膜进入缓冲腔体进行富集。样品分析完毕后开通电磁阀门进行差分抽气,把富集后的样品迅速抽出防止记忆效应 ...

ABSTRACT This paper examines the impact of the COVID‐19 pandemic on income and wealth inequality in Switzerland, with a particular focus on poverty dynamics and the role of the social security system. Using newly linked administrative tax data for four large cantons covering over a third of the Swiss population, we track changes in household income and

利用选择性萃取技术对表层沉积物(生物膜)中的锰氧化物、铁/锰氧化物及有机质进行选择性萃取分离,同时考察同步萃取下来的Cu,Zn的分离情况,并运用加和模型研究表层沉积物(生物膜)中各组分对自然水体中重金属Cu,Zn的富集能力。结果表明,生物膜对自然水体中重金属Cu,Zn的富集能力大于表层沉积物,表层沉积物(生物膜)中的金属(铁、锰)氧化物对重金属Cu,Zn的单位富集能力远远大于有机质(1~2个数量级),有机质对重金属的单位富集能力可忽略不计,金属(铁、锰)氧化物是表层沉积物(生物膜 ...

Tracing change in the public perception of plants: insights from archives and social media in China
As urbanization accelerates, historic gardens serve as vital cultural treasures that offer spiritual and cultural support to the public. This study proposes an innovative approach that merges historical records from the Qing Dynasty with contemporary social media data to explore changes in public perceptions of these gardens.
